MITOSIS
Makes cells IDENTICAL to parent
cell and IDENTICAL to each other
Makes TWO DIPLOID (2n) cells
MEIOSIS
Make cells DIFFERENT from parent
cell and DIFFERENT from each
other
Makes FOUR HAPLOID (1n) cells
(with ½ number of chromosomes)
Makes body (somatic) cells
All kinds of body cells can do this
Divides once
Copies DNA every time cell divides
Makes gametes (sperm & eggs)
Only testes and ovary cells do this
Divides twice; copies DNA once
(Skip Interphase II)
PROPHASE
NO synapsis / NO crossing over
ANAPHASE
NO segregation
NO independent assortment
ANAPHASE
chromatids separate
Used by all body cells for:
growth, repair injuries, replace worn
out cells;
PROPHASE I
Synapsis & crossing over
ANAPHASE I
Segregation & independent
assortment
ANAPHASE I
Homologous partners separate
ANAPHASE II
chromatids separate
Used by ovary/testes cells to
make sperm & eggs for sexual
reproduction (animals)
NO genetic recombination
Genetic recombination
